Patented Jan. 14, 1936 UNITED STATES cam, ADAMS, or ROCHELLE PARK, NEW JERSEY VEHICLE Application filed December 13, 1927. Serial No. 239,620.

"This invention relates to vehicles and it particularly relates to vehicles propelledby human power, the object of the invention being to provide a vehicle intended primarily for the amusement of children as well as for It'is, however, a further object of the invention to provide a vehicle of a construction which will allow also invalids to avail themselves of the device for their transportation;

it is a further object of the invention to provide means which will allow the owner of the same to travel with a greater speedthan is possible with the type of wagons now usually presented to boys of older age.

It is, in view of the purposes stated above, another object of the invention to provide such .a vehicle at a low price and which, though simple in construction, allows the operator to use it as a substitute for an automobile which in itself would be too dangerous to be entrusted to a boy.

In the following I am going to describe, by way of example, one preferred embodi ment of my new hand propelled vehicle, ref erence being had to the accompanying drawings, forming part of the specification; in said drawings Figure 1 is a top view of the vehicle, showing the propelling means and the braking device, the seat for the driver being notshown so as to render other parts visible;

Fig. 2 is a vertical sectional view along the a line 22 of the Figure 1, the seat of the driver being shown therein;

Figure 3 is a detail view of the rear mounting for the brake and clutch operating rod.

The frame-like body of the vehicle con-; sists of the side walls 11 and12 and of the horizontal braces 13, 14, 15 and 16 arranged horizontally and perpendicularly to the aforesaid sidewalls of the body so as to give the same greater stability. I

An axle 17 is secured to below a Wooden swivel joined block 18, or any other similar means, which furthermore is provided in the centerof its upper side with a stud or bolt 19 passing through and being rotarily arranged in an aperture (not shown) in-the center of r the brace 13 above which the stud19 is held by a nut 20; wheels 21 and 22 are operatively secured to the axle 17 at the sidewalls 11 and 12, respectively. Ashort shaft 23 is vertically and rotarily arranged in the center of the brace 14'; the upper end ofsaid shaft 23 is provided with an annular turn table 24 rigidly secured thereon in any suitable manner. In order to facilitate turning this table with. the feet, two studs or pedals 25 are vertically arranged on the table in a short suitable distance from each other. I

A sprocket wheel 26 is secured in any of the well known ways to the lower end of the shaft 23 and engages a sprocket chain 27 secured with its ends to the block 18 equidistantly from the bolt 19. A washer 53 is slipped over the bolt 19 andinterposed between brace 13 and block 18 so as to reduce friction between the latter parts. A crankshaft 28 is rotarily arranged in the front part-of the vehicle in suitable journals, (not shown) near the upper rim of the side walls 11 and'12; on its left side a flywheel 29 and on the right side a sprocketwheel 30 are secured in any of the well known waysto the crankshaft 28, the flywheel and the sprocket wheel being of the same diameter which is approximately the height of the crankshaft. The horizontal bars of the latter are provided with shells to protect thehands of the operator from injury by friction and adjoining these shell stirrups 31 and 32 are depending from the crankshaft 28. 33, represents the seat for the driver; in the rear of fthis seat an intermediate rotary shaft 34 is arranged horizontally and perpendicular to and in the sidewalls 11 and 12 in proper journals (not shown) the right 'end of this shaft is priovided witha flywheel35 and the left one with a sprocketwheel 36 of approximately .onehalf the diameter of the sprocketwheel 30,

both wheels being secured to the'shaft 34 in any suitable manner. A sprocket-chain 37 operatively engages the sprocket'wheels 30 and 36. In approximately the middle of shaft 3 1 a sprocketwheel 38 is rigidly secured in a suitablemanner, its diameter being approximately the same as that of sprocketwheel 30. v

In the rear of the vehicle a rotary axle 39 y is arrangedhorizontally and perendicularly to the side walls 11 and 12 in journals (not shown) and is provided with a wheel 54 and 55 at its ends, respectively; in approximately its middle a sprocketwheel 40, having a notch 41 in its hub, is loosely arranged thereon so as to engage the adjoining stationary wheel 42 having a projection 43 fitting into aforesaid notch 41, rigidly secured tothe axle 39, It

' is obvious that the sprocketwheel 40 thus acts 'pable of withstanding the heat caused by the friction between the pad and the brakewheel I 42 if they occasionally come to play on each other; the other side of the fork is split into two longer fingers 49 and 50 fitting into a groove in the hub of sprocketwheel 40 as indicated by Figure 2. i

Brackets 51 are secured below the body of the vehicle between theaxles 34 and 39 and a bar 52 slides within said'bracket in suitable ports (not shown) paralleLto thesaid axles 34 and 39. I v

Sprocket wheels 38 and 40 are operatively connected by a sprocket chain 56.

The operation of the vehicle is obvious. Theoperator turns the crankshaft 28 with his hands and directs the front wheels by having gearing means secured thereto, a rotary axle transversely arranged adjacent the rear of the body, having supporting wheels rigidly secured at its outer ends and a clutch intermediate said wheels, a spring actuated gearing wheel, slidably arranged on said rotary axle and adapted to operatively engage the clutch, and means for transmitting power from the crank to the intermediate shaft and to the rotary axle.

2; In a Vehicle the combination of a bodyand supporting wheels therefor, a hand crank mounted transversely of said body adjacent the front. thereof, a sprocket wheel secured to the outer end of said hand crank, foot stirrups rotatably supported on saidcrank and depending therefrom, a rotary shaft trans,- versely arranged in approximately the middle of the body and having sprocket wheel's, Se.- cured thereto, a rotary axle, transversely arranged adjacent the rear. of the body, having supporting wheels rigidly secured at its outer ends and a clutch intermediate said wheels, :1 spring actuated sprocket wheel, slidabl'yarranged on said rotary axle. and adapted to operatively engage the clutch, and a chain device for transmitting power from the sprocket wheel on, the crank to those on the intermediate shaft and, on the rotary axle,

CAR A MS,-v

actuating the turntable 24 either to the left 7 or to the right by putting one foot on each of the pedals 25 and pushing them to there spective side, If the vehicle is togo up-hill, the operator may step into the stirrups 81 and 32 and may thus actuate the crankshaft 28 with his hands andtfeet. If the car is to start, the operator steps on the pedal/17 and pushes it towards the sidewall 11 whereupon the brake pad disengages from the brake wheel 42 and thesprocketwheel 40 engages the same by having the notch 41 snap over the projection 43; if the vehicle is to stop, the pedal 47 is pushed towards the sidewall 12. Owing to the relations in the size of the diameters of the sprocketwheels engaging the crank shaft 34, the vehicle can be easily operated and I approximately the middle ofthe body and
